A statewide manhunt that focused on an Interstate 5 rest stop in northern San Diego County is now over.

Stephen Paul Clark has been arrested in San Francisco after eluding authorities in San Diego, according to law enforcement sources.

This week, Contra Costa County investigators began following the cell phone signal of the violent serial rapist.

The 45-year-old man was with an ex-girlfriend at the rest stop just south of Las Pulgas exit around 6 p.m. Wednesday when California Highway Patrol officers drove through the parking area.

Bay Area Rape Suspect Spotted

Officers in the Bay Area had asked Oceanside police to check out a rest stop because they'd been tracking Stephen Clark's cell phone and its signal brought them here. When officers got into the parking lot Clark jumped over a fence and started to run. Kelly McPherson reports.

Officers said Clark jumped over a fence and started to run.

A rape victim in the Bay Area identified Clark as the man who bound, gagged and threatened to kill her week officials said.

When Clark spotted the officers approaching him Wednesday, he told his ex-girlfriend that he didn’t want to get her involved in his situation but that she needed to jump over the fence and run with him.

Sexual Predator Remains At Large

She refused.

When interviewed by CHP, the woman told them she and Clark had traveled to San Diego to spend time at the beach. She said she had no idea he was suspected of a brutal rape in the Bay Area.

Investigators believe it was just a ploy so he could get close to the U.S. Mexico border so he could get out of the country.

The rest area was closed to the public for several hours as CHP and San Diego County Sheriff's investigators searched for Clark.

A helicopter helped in the search but eventually officers called off the search when Clark was not located.
